Unitronics UMI-0007CU-B1 variable frequency drive, a 0.75 kW three-phase 200-240 V AC input inverter for three-phase motor control, automation machinery, pumps, fans and conveyors.
£189.00
The Unitronics UMI-0007CU-B1 is a compact and high-performance AC variable frequency drive (VFD) from the Unitronics UMI-B1 UL series, designed for precise speed and torque control of three-phase motors in machinery, automation and industrial control applications. It helps improve machine efficiency, reduce energy consumption and deliver smooth motor operation in compact control panel installations.
This drive combines a compact B1 casing with advanced motor control features, including SVPWM, sensorless vector control, torque control and voltage auto-adjustment. Built-in communication capability, flexible I/O and integrated safety functionality make the UMI-0007CU-B1 a practical choice for machine builders and automation engineers requiring dependable small motor control.
With a rated output power of 0.75 kW / 1 HP and a three-phase 200–240 V AC input supply, the UMI-0007CU-B1 is ideal for compact conveyors, pumps, fans, packaging machinery and OEM automation systems. The drive includes Safe Torque Off (STO), built-in dynamic braking, forced air cooling and an IP20 enclosure for DIN rail or wall mounting.
Variable frequency drives such as the Unitronics UMI-0007CU-B1 regulate motor speed by adjusting output voltage and frequency. This allows machinery to operate more efficiently while improving process control and reducing stress on motors, belts, pumps, fans and mechanical components.
The UMI-B1 series is well suited to machine automation environments where compact installation, flexible communication and reliable motor control are essential. Its support for Modbus RTU and RS-485 communication enables integration with PLCs, HMIs and wider automation systems.
